Force exerted by a agitated fluid on vessel wall

AI Thread Summary
To calculate the pressure exerted by an agitated fluid on the walls of a non-pressurized vessel, consider the effects of extreme accelerations and decelerations, as these can significantly influence wall stress. Minor agitation typically has negligible impact, so designing for the liquid's mass with an appropriate safety factor is often sufficient. If agitation involves vibrations, it's crucial to address potential fatigue and resonance issues. Surge loading can also be managed with proper design considerations. Focus on critical areas, particularly the upper and lower parts of the container, and incorporate wave analysis, hydraulics, and the water hammer effect in your calculations.

How can I calculate the pressure exerted by a fluid on the walls of the vessel that is being agitated. The vessel is not pressurised. I have to calculate the resultant pressure on the walls to calculate the thickness of the vessel walls.

Please describe the problem in more detail .
 
Minor agitations won't do much to the vessel. Might as well just design it to hold the mass of the liquid with a sensible factor of safety.

The only way I could think of, that the agitation of liquid could have a reasonable effect on the walls of the vessel is if you are making it undergo quite extreme acceleration and deceleration (is the vessel on hydraulic jacks or something?). Then, perhaps you could simply consider the G forces.

If the agitation is in the form of vibrations, it's a different story altogether, as you have to start looking into fatigue and avoiding resonance.
 
@billy_boy

Surge loading and similar problems are not particularly difficult to deal with . Could you could just give us a clearer idea about what you are trying to design ?
 
Dan S thank you. This is the answer i was looking for. It is a very simple reaction vessel

Where do you think is the critical areas that needs attention? In the upper or the lower part of the container?
Calculation may involve wave analysis, hydraulics and water hammer effect.
 
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
